PHASE DIFFERENCE BLANK FILM, PHASE DIFFERENCE PLATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE:To provide the phase difference blank film or phase difference plate which can afford a liquid crystal display panel solving the problems of coloration and contrast.ratio which are heretofore unsolved. CONSTITUTION:A stretched film is obtd. by at least uniaxially stretching a high-polymer film having >=1.60 refractive index nD, <=30.0 Abbe number nuD and 60 to 160 deg.C glass transition point Tg. The retardation value R of the stretched film is set at 60 to 1000nm and the wavelength dispersion value nuRF at >=1.10 The phase difference plate constituted by laminating an optically isotropic film or at least one surface of the phase difference blank film consisting of such stretched film is used for hue compensation of the liquid crystal display panel.
